An easy way to do garlic bread if your oven is filled with other dinner items.

Margarine
3 crushed garlic cloves (or 1 tsp garlic powder)
1 loaf french bread

Cut loaf into two inch slices, but not cutting through the bottom of the loaf. In a small container, combine garlic with margarine, making sure it is thoroughly mixed. Spread garlic butter on both sides of each bread slice. Place on a couple of paper towels and heat on medium for one minute. Continue heating on medium at 15 second intervals until garlic butter is melted.
